The E-flite 40A Pro Switch-Mode BEC Brushless ESC is a high-quality, innovative and efficient sensorless brushless electronic speed control with an integrated switch-mode BEC. It can operate without the need for a separate receiver battery to power your servos and receivers, saving you weight and complication. It is capable of up to 40 amps continuous current when using 3- to 6-series Li-Po battery packs. You can drive up to 7 analog or 6 digital standard-sized servos with the BEC on any recommended input voltage. This ESC also features an exposed, finned heat sink aluminum case with lightweight plastic endcaps. Additional features include safe power arming along with advanced programmable features such as low voltage cutoff, braking, timing, throttle input range, and more, making this truly a ‘pro series’ speed control.
